Turn Signal Left On Chime
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The turn signal left on or turn signal minder chime uses both odometer and turn signal status messages. The turn signal left on chime sounds a repetitive 1-second chime through the front speakers when the vehicle is driven with the turn signal on for more than 3.2 km (2.0 miles).
The IPC receives the turn signal switch status from the GWM over the HS-CAN3.
The GWM receives the turn signal switch status from the BCM over the HS-CAN1.
When a chime request is received, the IPC sends the IPC chime request message to the ACM and the audio DSP to sound the chime.
